Fortinet is rallying today as part of a broader surge in cybersecurity stocks, with peers like Zscaler and Palo Alto Networks also posting significant gains. Investor sentiment remains bullish following a wave of positive commentary over the weekend that highlighted the company as a top beneficiary of the growing demand for agentic AI and advanced security infrastructure. This optimism builds on momentum from earlier in the week, where analysts reaffirmed the company's growth potential despite a 119.9% rally over the past six months, citing its AI-driven product demand and strong guidance.
